Abstract: An electrical device which comprises first and second laminar electrodes and a laminar PTC resistive element sandwiched between them, the device comprising (a) a main portion which comprises a main part of the first electrode, a main part of the second electrode, and a main part of the resistive element; and (b) a first connection leg which extends away from the main portion and which comprises a first leg part of the first electrode which is integral with the main part of the first electrode, and a first leg part of the resistive element which is integral with the main part of the resistive element. Such devices can be secured to circuit boards in a variety of ways, and to elastically deformed terminals.

Abstract: Electrical devices, particularly circuit protection devices, contain conductive polymer elements whose edges are formed by breaking the conductive polymer element, along a desired path, without the introduction of any solid body into the element. The resulting cohesive failure of the conductive polymer produces a distinctive fractured surface. One method of preparing such devices involves etching fracture channels in the electrodes of a plaque containing a PTC conductive polymer element sandwiched between metal foil electrodes, and then snapping the plaque along the fracture channels to form individual devices. The figure illustrates a circuit protection device made in this way.

Abstract: Laminar electrical devices, in particular circuit protection devices, contain two laminar electrodes (13,15), with a PTC element (17) between them, and a cross-conductor (51) which passes through the thickness of the device and contacts one only of the two electrodes. This permits connection to both electrodes from the same side of the device. The device also includes layers of solder (64,65,66,67) on the areas of the device through which connection is made, and separation and/or masking members (81,82,85) which (a) reduce the danger of short circuits formed by solder flow during installation of the device and/or (b) provide a site for permanent marking of the device.
